ok:
I'll take a second stab.....backyard folks sometimes add lights for heat....(I don't btw)...
On another note here's what my crew is doing.....my late blooming Dork, has laid three eggs in the past four days.....one or both Orps are combined lay about 3 per week.....My GLWs are both molting and haven't laid an egg in a couple of months...and the BCMs have both laid regularly since the fall....
and just to re-enforce how weird things are, I have a baby roo who is about 7mos old and hasen't crowed once....though he did show some interest in the dork...(she made a fuss and he gave up)...
And, just because I am green with envy with coops full of broodies, or baters full of eggs, I decided to start my seedling today....
The only thing with that theory though is that adding heat is an even bigger no no then adding light...
